Penicillium spp. are the major postharvest pathogens of citrus fruit in Mediterranean climatic regions. The induction of natural resistance constitutes one of the most promising alternatives to avoid the environmental contamination and health problems caused by chemical fungicides. To understand the bases of the induction of resistance in citrus fruit against Penicillium digitatum, we have used...

Mandarin (Citrus reticulata), a non-climacteric fruit, is an economically important fruit worldwide. The mechanism underlying senescence of non-climacteric fruit is poorly understood. In this study, a gel-based proteomic study followed by LC-ESI-MS/MS analysis was carried out to investigate the proteomic changes involved in peel senescence in harvested mandarin "Shatangju" fruit stored for 18 d...

BACKGROUND Recently, essential oils and extracts derived from plants have received much interest as potential bio-active agents against mosquito vectors. METHODS The essential oils extract from fresh peel of ripe fruit of Citrus aurantium and Citrus paradisi were tested against mosquito vector Anopheles stephensi (Diptera: Culicidae) under laboratory condition. Then chemical composition of th...

'Persian' acid lime (PAL) is the most important triploid commercial citrus crop planted in the world. Little is known about the genetic variability of the selections used in Brazil. Therefore, 25 genotypes originating from the PAL, and three control species, Citrus sunki, C. limon, and C. aurantiifolia, were assessed using inter-simple sequence repeat (ISSR) and inter-retrotransposon amplified ...

Citrus plants are the rich source of secondary metabolites which includes alkaloids, steroids, tanins, flavonoids, phenols and polyphenols. Having the rich source of polyphenols and natural flavonoids draw attention to screen the phytochemical compounds and their beneficial activities from different solvents. The present investigation explore the in vitro antioxidant activity of orange (Citrus ...

Continued application of synthetic insecticides arise development of resistance and pollution of the environment. Laboratory experiments were conducted to test the efficacy of products of orange (Citrus sinensis) peels in the control of the stored products beetle Zabrotes subfasciatus (L) in stored haricot beans (latin name). Different levels of the extracts and essential oil of Citrus sinensis...

That the vitamin C (ascorbic acid) con tent of a fruit is dependent upon the in tensity of incident light was suggested by findings of Zilva and his associates (10) reported in 1935. These investigators found that the red peel of Bramley's Seedling apples contained twice as much vitamin C as the green peel. Although they did not mention light as a factor in the production of this difference in ...

Industrial by-product like orange peel plays an important role in pectin manufacture. The objective of this article was to extract pectin from peel of Citrus sinensis and to study the effect of its incorporation on the quality of yogurt during the period of fermentation and postacidification. Physicochemical, organoleptic, and rheological properties of yogurt prepared with pectin were studied i...
